Technic:
By transisthmic approach,
we are going to treat all the nodule by successively spots of radiofrequency deposit.
This approach permits to stay far away from main vascular or nervous structure,
oesophagus and trachea.
It is the « Moving shot technic » described by Professor Baek from South Korea more than 10 years ago.
In our study we used Monopolar 18G (1,01mm),
cooled,
tip active 10mm RF electrode and Generator VIVA RF (35-45 W).
Patients:
From Oct 2016 to June 2018, 52 patients (41 F.
/ 11 M.) with benign thyroid nodules responsible of cervical discomfort refusing surgery undergone US-RadioFrequency ablation.
Their mean age was 45 years (30-73) : 61 nodules have been treated.
3 patients have already treated for thyroid pathology : 2 by surgery and 1 by alcoolisation.
More than half have bilateral nodules and 1 MultiNodular Goiter has been treated.
There are 2 Autonomously Functioning Thyroid Nodules.
The discomfort was various and symptomatology could be associated: trouble of swallowing and cosmetic problems were the most common symptoms.
Inclusion :
All are Imaging and Cytologic of Benign Nodules according inclusion’s criteria of mainly international studies about RadioFrequency in thyroid:
-We used EU-TIRADS ultrasound classification : in our study nodules are mostly Eu-T3.
-2 US-guided FNA was performed on each nodule and it was answered in Bethesda system 2010 and 2017 : 88,52% patients have 2 cytology Bethesda 2 and 7 nodules have 1 cytology Bethesda 3.
Analysis :
The imaging response was verified in 1,
6 an 12 months after RadioFrequency.
The Clinical response was tested by a Visual Analogical Scale (0-10) : we wanted to measure discomfort of the patient before and after RF and his global satisfaction for this treatment
Complications were noted.
And we test biological affect by TSH blood measure after 2 months.
